Breaking blocks near chunk edges causes extreme amounts of lag
If you chop down a tree near the edge of a chunk, evne of powerful systems like mine, the game will drop to 10/20 fps for about a second and then will catchup.
Replication this is very easy:
- load up a new world on any 1.14.x version without the OptiFine mod
- Press F3+G to show the chunk edges
- Chop down a tree in Survival Mode
